Starting in 2026, all Matter integration and testing will require the CSA Interop Test. For more information, see the CSA Interop Test Lab transition page.

CSA Interop Test Lab integration transition

To support our growing smart home ecosystem and provide a more streamlined process, Google will use the Connectivity Standards Alliance Interop Test Lab (CSA ITL) for all Google Matter integration for manufacturers that want the Works with Google Home (WWGH) badge.

From now until the end of 2025, we will slowly introduce and encourage you to test your device through Connectivity Standards Alliance (Alliance) Interop Test Lab and submit the test results when certifying your Matter device with Google. At the beginning of 2026, we will only accept the Alliance ITL test results for Google Matter integration.

This document provides key dates and details for a seamless integration testing and certification.

Timeline

The following table defines the terms and timelines related to the changes. You'll receive a reminder email prior to update, which will take place in phases.

Dates	Details
Starting now	There is an option to include the CSA ITL test results for testing in the Google Home Developer Console when certifying Matter supported devices. Update the Developer Console to include more device types to accept the ITL test results.
Phase 2	Dual-Path option. Accept all Matter device types' ITL test results for certification. Google Home Test Suite is still supported, however, we highly encourage you to start testing through ITL.
Phase 3	Full transition to ITL test results for certification. Test Suite will be disabled and the ITL test results will be the only option to obtain the WWGH badge.

Who is impacted by this transition?

All developers certifying a Matter device and want to obtain the WWGH badge.

What's changing?

The Test Suite will only be used for development purposes.
We will only accept ITL test results for Google Matter integration and certification.

What's not changing?

The certification process will remain the same. A ITL test results will be needed in place of using Test Suite to test your device.
Your user and product experiences aren't changing.

How will this help my development process?

The Developer Console supports your development journey from learning to launching. We streamlined the certification review process so you no longer need to test the device yourself.

How do I send devices to CSA ITL?

To send your devices to ITL, read the Steps to Submitting a Product for Testing.

Where is the technical documentation?

All technical documentation, codelabs, and tools are available here in the Matter documentation section of this site. You'll also see relevant documentation in the console as you move through the different development phases.
